Benefits of our current sensing amplifiers 


Low-drift architecture

Achieve low drift over a wide temperature range with our zero-drift architecture and precision matched, integrated gain resistors. 


High accuracy

Increase overall system performance and efficiency with higher accuracy due to low input offset and low gain error, enabling lower ohmic shunts and minimizing power dissipation.


Wide common-mode input range

Measure common-mode voltages beyond your amplifier’s supply voltage rail (from 120 V to -22 V) to address high-voltage system needs, like batteries in electric vehicles and motor-control systems.

Flexible current-sensing solutions for your design

Achieve accurate and fast current sensing in every system

Whether you need to detect an overcurrent fault, improve system efficiency, or provide closed-loop feedback, TI's large portfolio of current-sensing solutions enables industry-leading accuracy for a range of common-mode voltages and temperatures – without sacrificing system size, complexity or cost. Through decades of experience, we have developed leading-edge current-sensing technology that empowers engineers to achieve maximum system performance, power efficiency and reliability.
